Shopware exposes sensitive user information via CSV export mapping
Impact
Malicious actors can exploit this finding to export sensitive customer information from a Shopware application, including password hashes and password reset tokens. In SaaS deployments, this primarily affects customer accounts. In on-premise deployments, however, it also includes the hashes and recovery tokens of administrator-level accounts, which increases the potential impact. This risk is noteworthy because users may reuse the same or similar passwords across different services. In such cases, exposed hashes could allow attackers to recover credentials that might also be valid outside of Shopware.
Description
Sensitive information disclosure occurs when an application inadvertently displays sensitive information to its users. Depending on the context, websites can leak all kinds of information including: • Data regarding other users, such as usernames and/or e-mail addresses • Sensitive commercial data such as customer names • Technical details about the website and/or the underlying infrastructure Disclosing technical details, such as detailed version information, allows malicious actors to look for targeted vulnerabilities and/or misconfigurations in the application or in the underlying infrastructure. In addition, an application is more likely to be targeted by attacks that specifically target a particular version of the software used.
Applicability
The Shopware application exposes sensitive information to users within the export section. The Shopware application allows admins to import and export data within the application. To do this import/export profiles can be created. These profiles tell the application which tables within the database map to which columns in the generated file. During testing it was noticed that sensitive information such as password hashes or reset codes can also be included within the export. This can be done by creating a custom mapping that includes these fields within the export. To exploit this vulnerability, an account with permissions to create import/export profiles and to create exports, is required.
Reproduction
To reproduce this vulnerability, the steps below can be followed.
- Log in to Shopware application with an admin account capable of creating import/export profiles and creating exports
- Create a new import/export profile
- Add a new mapping for the ‘password’ database entry
- Create an export using the new profile
- Notice that the password hashes of the users are available within the export file.

Frequently Asked Questions
A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.
CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.
A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.
Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.
Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.
SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
